I have a plate of 3 light switches that's just taking up too much real-estate. See picture below:

As you can see, I've got a bookcase right next to it, and I could use a little more room there. The corner itself looks like a 4x4 inch post. The other wall has a pantry door just after the corner. Can't move the switches around the corner, and they're already as far to the right as they can. One possibility left: going small.

I've looked into triple rocker switches, but two of my three switches are actually three-ways that I would like to keep. Apparently three-way switches don't come smaller than the standard.

You can install one keypad in place of all 3 of those switches. The keypads can generally control one local load (although Simply Automated makes one that controls two loads). Since the other two are already 3-way switches, you can use the keypad to control those remotely.

The other two 3-way switches (that are not located in this box) get converted to single load smart switches, and are what actually control the load. By linking up the keypad to control the other two remote switches, you effectively get all three.

I personally have Insteon stuff in my house now (including both products here) but I'm not a huge fan. It's very easy to program (you just hold down buttons on the keypads) but it's also very limiting in some cases, such as not being able to have a scene that turns some lights on, but others off (you can have it turn different lights on to different levels, but 0% doesn't work).

I have not yet used SimplyAutomated's stuff (other than trying out the PC-based programming app) but it looks much much more powerful. They have better keypad hardware/options, WAY more control options (such as what happens on one press vs double-press vs triple-press vs hold), but it also looks a bit more complicated to set up, and requires a PC and PC<->UPB interface.
